SAUSAGE-MEAT CUTTER.

SPECIFICATION forming part of Letters Patent No. 324,835, dated August25, 1885.

Application filed March 28, 1885. (No model.)

T0 at whom it may concern.-

Be it known that we, JOHN R. GRATH and THoMAs K. Warson, citizens of theUnited States, residing, respectively, at Lorah and Leinbach, both ofthe county of Berks, State of Pennsylvania, have invented a new anduseful Improvemcntin SausageMea-t Out-ters, of which the following is aspecification.

Our invention relates to improvements in meat-cutting machines in whichtwin rollers with inserted knives operate in conjunction with a seriesof fixed knives secured in the lower portion of the machine central tothe pair and in the upper portion of the machine coincident with theouter surfaces of the rolls.

The object of the improvement is to secure a more uniform product,cleanly out without shredding, and a machine that will operate quickerand with less labor than those now in the market, and which is readilyadapted to be run by steam or manual power. These objects we attain inthe use of themechanism shown in the accompanying drawings,in whichsimilar letters indicate similar parts.

Figure 1 represents in perspective the completed machine with the topthrown back,disclosing the rolls in place, and showing the fixed knivesat the sides of the top. Fig. 2 is an elevation of the operating side ofthe machine, showing gearing and crank. Fig. 3 is a cross-sectionalelevation taken just inside of the machine at the working end, detailingthe interior construction, and showing both rolls, side, and centralcutters in place. Fig. 4 is a plan of the top of the machine, showingthe hopper and feeding aperture. Fig. 5 represents detail views, upon anenlarged scale, of the roll, central and side knives or cutters; Fig.6,a longitudinal section of a portion of the box, exhibiting thearrangement of the side knives.

A represents the lower end piece of the ma chine on the operating side,-A, the same piece upon the opposite end; A, an aperture for thedischarge of the cut material. A rep resents the upper end pieces of themachine, being similar at both ends.

For the purpose of facilitating the construc tion and giving anincreased steadiness to the machine when closed, the double concaves Band D are separated by the intermediate re movable pieces,@ 0, the endsA A being made of such height where they-meet the front and rear of B asto project above the same about one-half inch, and the top edge of theends being drawn through said points, and the centers of the rollshaftsform an apex, A, the ends A being formed at a corresponding reverseangle to mate therewith. This gives an opportunity to introduce thescrews A into the ends of the intermediates, and locks the top betweenthe sides when closed.

The pieces D B, forming the top and bottom concaves of themachine,aresimilarly grooved at B D, the center longitudinally forming aridge, B D", which in the upper piece, D, re tains the materialintroduced in contact with the roll-knives as it passes from the feedingto the discharging end of the machine. The lower piece has its ridge Bsawed across at right angles with the grooves for the insertion of aseries of knives, K, placed in said sawkerfs, arranged to have thedistance between the same gradually diminish from the feeding toward thedischarging end of the same. The pieces 0 G are also saw-kerted in asimilar manner to the ridge B and have knives or cutters L securedtherein. These pieces are removably secured in place by the screws A atthe ends and by screws A through the body of the same.

A hopper,E,'is placed upon the top of the machine.

Two llard-wood rolls, F F, provided with shafts F, are journaled inseats Ftin. the ends of the machine, and have a series of knives orcutters,J, setin sawkcrfs at three equidistant points upon theircircumference,and with their heads upon a spiral of agraduallydecreasing pitch traced from the feeding toward the discharging end of the machine, the time which shall be consumed by thematerial in, passing from the feeding to the discharging end beingregulated by the change in the pitch between the two ends of the roll.

Gears G are placed upon the shafts F, and a crank, H, and handle I servefor operating the same. As the gears are direct, the cutters or knives Jare placed upon the rolls in reverse spiral to each other, the out beingmade downward toward the central ridge, D", and knives K, and upwardtoward the side knives, L. This insures a clean out between theintersecting cutting surfaces, and being a gradual one, commencing atthe lowest point of the several cutters and the depth of cut graduallyincreasing until the highest point of the same is passed, involves verylittle labor in operating the machine.

The machine has hinges 1% upon one side, and hook M with catch M uponthe opposite side, whereby it is retained in a closed position when inuse.

The knives J, K, and L are made of sheetst-eel in the form shown, andafter sharpening are driven into their respective saw-kerfs, which areso adjusted relatively to each other that when the rolls F with theknives J revolve said knives shall just pass the cuttingfaces of theknives K L. A feeding-aperture, D and discharging-aperture 13 completethe machine, which is shown in Fig. 1 a seated upon a bench, P, wit-hcleats N.

We are aware that twin-roller meat-cutters have been used prior to ourimprovement, (see Patent No. 88,666, April 6, 1869, to J. G. Perry butour improvement thereon, whereby the knives or cutters are madeadjustably removable for tempering and sharpening,adds to the life ofthe cutter, to the ease of cutting, and to the quantity of meat whichmay be cut in a given time, making our machine an essential advance uponall prior twin cutters.

Having shown the construction, operation, and advantages of our machine,we desire to secure by Letters Patent the following claim thereon: p

A twin roller meat-cutter consisting, essentially, of the followingelements: top and bottom coneaves, D B, having feeding-aperture D anddischarge-aperture B intermediate pieces, 0 0, ends A, A, and A hopperE, cutters or knives L L, rolls F F, with cutters or knives J andcentral knives or cutters, K, all of said cutters being removabl y fixedin sawkerfs, gear G, and crank H, the parts being combined substantiallyas and for the purpose as shown and described.
